Russian Martial Arts are not based on
techniques; they are based on training concepts, laws of motion, and
"what is" in the moment of contact. This is a far cry from the
waza (technique) based mentality of many Eastern arts, where
the bulk of instruction is through rehearsing pre-constructed sets
instead of improvising inside of a scientific structure. Since
there is no "technique" to do right or wrong, the learning curve is
shorter. What makes this truly effective is that being struck
is the penalty for less-than-optimal performance. Pain is
reduced to "biofeedback" that you should do something differently,
and when it stops hurting then you've got it right!
